HORSE-RAKE.

SPECIFICATION forming part of Letters Patent No. 225,602, dated March 16, 1880. Application iilecl September 5, 1879.

To all 'whom it may concern:

Be it known that I, HENRY C. HEECEEL- RODE, of Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Horse Hay-Rakes; and Ido hereby declare the following to be a full, clear, and exact description of the same. My invention relates to that class of horse hay-rakes in which ratchets on the wheelhubs, 1o and revolving therewith, are employed to elevate the rake-head by the progressive motion of the machine and at the will of the driver.

My improvements consist in the employment and arrangement ofcertain novel devices for causing the teeth to be automatically raised to discharge the collected loads at the will of the operator, as will be herewith set forth, and specifically claimed.

In the accompanying drawings, Figure l is a plan view of a horse hay-rake containing my improvements. Fig. 2 is a side elevationV of the same through the line a: .r of Fig. 1. Fig. 3 is a front eleva-tion of the machine. Fig. 4c is an enlarged view of my improved adjustable dog and its attachments.

The frame-'work of the rake may be of the ordinary or any suitable construction.

The tilting Wooden axle A, which in this instance is the rake-head, is hung by spindles to the hubs of the supporting and carriage wheels B, and the rake-teeth C are attached to this head in any suitable way, either Vby separate metal castings or by clamping theirends between the head and a retaining-strip, ,as shown in the drawings.

.The thills D are united at their rear ends by the cross-bar E, from which the cleaner-sticks F project in the usual manner, as shown. G and H are the ordinary cross-bars, which support the drivers seat I. This frame-work,

consisting of the thills, cross-bars, and their attachments, is connected to the rake-head or axle bymeans of the strap-hinges J, which project from the cross-bar E, and are pivoted in any suitable way to the axle. In this instance these pivoted points coincide with the axes of revolution of the carriage-wheels.

The wheel-spindles a are clamped between two castings, b and c, to the under side of each 5o end of the rake-head A, and from which they project to receive the hubs of the wheels. The casting b has ears cl formed integral with it, which ears are iiush with the ends of the head A, and serve as supports, to which arebolted the shields or casings K, as shown. 55 These shields are cylindrical metal drums, with their outer ends open, and are of sufficient diameter t'o receive the ratchet-wheels G", which are concentric with the Wheels B, and are bolted or otherwise fastened with an interven- 6o ing disk, f, to the wheel-hubs. The disksl f serve as covers to the open ends of the drums or shields K, as indicated.

Upon each end of the upper side of the head A are fastened castings g, provided with bearing-ears, as shown, and upon the upper side of the head, at or near its middle, is a casting,

h, of the shape shown, also provided with ears. These bearings at the ends and center of the head A support a torsion-rod, L, carrying upon 7o each end a dog, j, of the shape shown, which can v be thrown into gear with the inclosed ratchets by means of Aan opening in the periphery of the drum.

Between the ears of thecasting h is a slotted arm, Z, of the shape shown, which is keyed or otherwise rigidly fastened upon the torsionrod; and the torsion-rod may be either one entire rod, running through the arm Z, or it may be divided, as in this instance, with its inner 8o adjacent ends secured in said arm. A A chain,

m, extends from the upper` end of the arm Z, and is fastenedto the seat-beam, as shown, and the arm Z is held back in the position shown in Fig. 2 by means of a spiral spring, n, 8 5 recessed in the lower front part of the bracket h, and bearing against a projecting lip, o, which forms part of said arm Z, as shown. In the rear part of the same bracket h is pivoted a gravitating-latch, p, which inclines forward 9o and passes through the slotor opening in the arm Z, as represented. There is anotch cutin the under edge of this latch, which, when the arm lis drawn forward by the drivers pressing his foot upon the chain, catches over the lower edge of the slot or opening in the arm, and thus holds it locked. Drawing the arm Z forward, as thus described, turns the torsion-rod and brings the dogs upon its ends into engagement with the ratchets, and thus effects a lock roo between the rake-head and the carriage-wheels. As the wheels continue to revolve the rake-head participates in the motion and the teeth are elevated. When the teeth have been carried up sufficiently to discharge the collected load the nose of the latch p comes in contact with a projection, k, or any stop placed upon the crossbar E or other adjacent part of the framework, and is forced out of engagement with the arm l. The arm l, being thus released, is forced back to its normal position by the spring n and, as the dogs are connected with this arm by the intermediate torsion-rod, they are lifted out of engagement with the ratchets, and the rake-head and the teeth being thus freed from the wheels, they are brought by their gravity back to raking position.

The novel and essential feature of my invention is illustrated in Fig. 4 5 and it consists in provdin g for the adjustment of the dogs upon the torsion-rod in the following manner: The outer projecting ends of the torsion-rod are made square or polygonal in section, and over this portion is'irst slipped the sleeve s, having a coincident bore. This sleeve carries upon its inner end a disk or ilange whose outer margin is notched or serrated, as shown. The inner face of the dog is similarly notched or serrated, as seen, and when it is slipped over the sleeve s the two notched faces come together and for-m a lock. A nut, t, screwed upon the end of the rod, which is threaded, holds the serrated faces together. By loosening this nut sufficiently to disengage the serrated faces the dog can be adjusted as desired, and then can be clamped, as before described. This is a very essential feature to the practical workin g of a rakehavin g a torsion-rod to throw the dogs into engagement with ratchets upon the hubs, for even should the dogs be properly adjusted in the shop the torsion-rod may loose some of its elasticity by use and a new adjustment of the dogs would be required.

By my device any farmer can regulate the machine in the eld.

M represents the usual slotted guide-bar, attached to the head at its rear in the usual way; and if desired the machine may have a handlever, which can be used independently of the automatic dumping devices.

lI am aware that it is not new toemploy a torsion-rod for effeetin g the engagement of the dogs with the ratchets and for securing the elevation of the teeth whether the machine is advancing or turning 5 but What I claim as new, and desire to secure by Letters Patent, is-

1. In a horse hay-rake, the combination, with ratchets revolving with the carriagewheels, and a torsion-rod mounted on the rakehead, of dogs made adj ustable upon the ends of said rod, whereby the relations of the parts enumerated can be adjusted when desired, as set forth.

2. The dogs j, having 4serrations or detents on their inner faces, in combination with disks or collars secured to the ends of the torsionrod and having coincident serrations or de# tents, as set forth.
